The client platform for UK practices
Live HMRC status across every tax, agent authorisation in clicks, client chasing and birthday emails, all under your brand. Built and run live inside a real practice.
No card required. Free up to 10 clients. Add your own branding any time.
One platform, modular
Every firm gets the platform free for its first 10 clients. Turn on the modules that fit how you work. Connect Karbon, or import your list.
Live HMRC status across VAT, PAYE, Corporation Tax and Self Assessment, the moment anything changes: what's owed, what's paid, what's outstanding, penalties and interest, in plain English. Smart, ready-to-send client emails for every position. Free for your first 10 clients, then £1/month per person and £2 per business, every tax included.
Included with paid Tax Compliance
Onboard a new client's HMRC authority without the paperwork. Request authorisation in clicks: VAT instantly via the digital handshake, and Self Assessment, PAYE, CIS and Corporation Tax via the authorisation-code journey. We even chase the client for the code for you, with a polite branded sequence, and enter it back to HMRC automatically once they send it.
Part of any paid Tax Compliance subscription (not on the free tier).
Add-on

See it in action
Every client's live HMRC position becomes a tidy app that nudges them before deadlines, with ready-made emails from your firm. They feel looked after; you stop chasing.
The problem
Reminding clients of deadlines and asking for information eats time you can't bill, every quarter.
They forget a VAT return or set nothing aside, then it lands on you to firefight the penalty.
New clients stall on HMRC authorisation paperwork and posted codes nobody chases. Doddletax does it for you.
How it works
Connect HMRC and bring clients from Karbon or a quick import. Your live tax data flows in. No spreadsheets.
Request authority for any client in clicks, then switch on the modules you want, and add branding any time.
Clients get the right nudge the moment HMRC changes; you get a dashboard for the full picture.
Built in a practice
Doddletax was built and is run live inside an ACCA Chartered accountancy practice. It started as the tool we wanted for our own clients, on our own HMRC data.
That means it fits how a practice actually works, not how a software team imagines it does.
Peace of mind
The reminders, the authorisation chasing and the data collection all happen on their own. Your team gets billable time back instead of sending the same emails again and again.
Clients are nudged the moment HMRC changes, so missed deadlines and last-minute scrambles quietly stop happening. Less risk for them, less firefighting for you.
A branded app and thoughtful touches are a service clients genuinely want. The firms that offer it keep clients longer, so it pays for itself well before the bill arrives.
Your data stays encrypted and secure on a platform built and run inside a real ACCA Chartered practice. It runs automatically in the background, so you can simply trust it to do the right thing for every client.
Pricing
£1/month per person, £2 per business. Every tax we cover is included, HMRC authorisation is included, and your first 10 clients are free. Add-ons priced separately.
